This is a Switzerland national team away football shirt from season 2011-13. Made by Puma; size is ADULT XXXL (but please see measurements below).
The shirt is 100% polyester; the national crest and manufacturer's + sponsor logo are embroidered. It can be machine-washed but is not suitable for the tumble-dryer (or the ironing board).
It measures 26 inches (66cm) from armpit to armpit and 33.5 inches (84cm) from collar to bottom hem - being ever so slightly longer at the back.
Brand new (with tags) but there's one pulled thread (see last photo) and a handful of small clicks/minor deterioration.
Absolutely genuine - no copies, fakes or imports of dubious origin here.
For overseas buyers, I only ship Airmail - Surface Mail may be slightly cheaper but is considerably less dependable.
